The design and experimental characterization of a burner is described, which has favourable characteristics for the accurate calibration of a range of optical thermometry techniques. The burner supports stable laminar flames and combines many of the advantages of several widely used burner designs without their disadvantages. It permits the application of point measurement techniques, line-of-s...

A self-sustained porous burner without a sprayed atomizer was built for diesel oil. It consisted of metal fiber felt as an evaporator upstream and ceramic foam emitter downstream. The liquid fuel underwent film boiling in the rapidly evaporated by heat recirculated from to through intense irradiative flux. effect structure its installation location on performance investigated. results indicated...

One of the techniques of minor actinides transmutation is to recycle these nuclides into fission reactors. Two concepts of a minor actinides burner reactor with very hard neutron energy spectrum as well as very high neutronjlux me discussed. The fuel cycle facilities for these burner reactors am assessed to discuss the technical feasibili~ of these reactors. Transmutation of minor actinide in b...

A three-dimensional laminar non-buoyant diffusion flame was studied with the objective of improving the understanding of the soot production. The flame originated from a porous ethylene burner discharging into a laminar boundary layer. Soot volume fractions were measured using Laser-Induced Incandescence (LII) and the spontaneous emission from CH∗ was determined using chemiluminescence. The mai...

The current work presents the results of an experimental investigation of gas-phase combustion synthesis of silica (SiO2) particles using a multi-element diffusion flame burner (MEDB, a Hencken burner). Silane (SiH4) was added to hydrogen/oxygen/argon (H2/O2/Ar) flames to produce SiO2 nanoparticles at various burner operating conditions ( 0.47–2.16). To characterize the burner performance, temp...

Thrust and fire safety are among NASA’s major concerns in the fulfillment of its mission on Mars Exploration, especially the missions that planned to bring astronauts to and back from the Red Planet. Responding to these concerns, the research studied the burning characteristics and extinction of diffusion flames in space, which are different from those on Earth due to the lack of gravity. Becau...

A metal fiber burner is proposed for structural thermal tests the test model of hypersonic vehicles. In order to guide design burner, we conduct Fluent simulations on a cylindrical with properly selected diffusion model, heat transfer between gas and solid phase, radiation porous media, gaseous combustion chemistry mechanism. After validating simulation, heating characteristics were further ana...
